No, not in the movies. however a jedi that looks like shaak ti is shot down on a speeder in order 66. but she gets killed in the force unleashed video game so, that jedi could be ahsoka but it is probably not.
The person in the speeder was Stass Allie. A human female with an odd hair band. Shaak Ti is the character in the Force unleashed. She is the one last survivor of the Jedi counsel(Joda and Obi Won are the others) So Asoka's death is till unknown till the last clone wars episode comes out.
